Ground adjustable P-LINE propellers are designed for applications such as powered paragliders, trikes, light motor hang-gliders and airboats with variety of engines with power output limit up to 44 kW(60 HP) (dependent on propeller model) and reduction gears mostly in pusher arrangement. P-LINE propellers are available in 2 or 3-blade configuration.

P-LINE propellers are very efficient which gives an advantage of high thrust and low noise during running. They are lightweight also, thanks to modern technologies used in production process which is resulting in very low inertia momentum, meaning high manoeuvrability for the pilot and quick throttle response.

The biggest benefit of P-LINE propellers is ability to adjust blade pitch, enabling the pilot to adjust characteristic of the propeller to his likings, actual weather conditions or engine parameters.

Construction & technology

Technological design of P-LINE propellers is based on hybrid carbon/glass fibre or full carbon fibre structure (dependent on propeller model) with increased elasticity module and epoxy resin. Materials used in construction have elastic properties which make the propellers damage and bad weather conditions resistant. The paint that covers blades guarantees high contamination resistance and slow exploitation wear.

The hub is lightweight, high strength two piece construction that enables ground blade adjustments. It is rust protected by anodized layer. Hub production uses best sort of duraluminium 7075 and high precision CNC machining.
